Metabolite Identification
Common NameNitroxinil
Description4-hydroxy-3-iodo-5-nitrobenzonitrile, also known as nitroxynil or deldrax, belongs to the class of organic compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. 4-hydroxy-3-iodo-5-nitrobenzonitrile is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Nitroxinil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nitroxinil is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
